UILongPressGestureRecognizer gets called twice when pressing down

I am detecting if the user has pressed down for 2 seconds:

UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress:)]; longPress.minimumPressDuration = 2.0; [self addGestureRecognizer:longPress]; [longPress release];

We had some fun using Leap Motion - gesture recognition device at the Pan-Pearson Hackathon on June 6th and 7th. We built an app for use in Kiosks at Hotel Lobbies, Office receptions, Libraries, Bus Billboards etc.

The app allows users to consume content from DK Travel Guides, FT Business News and Longman Dictionary - all via touch-less, gesture recognition technology.

We used the Leap-Motion Java API to process the motion / gesture data from the Leap-Motion device. This processed data was then relayed to the web-app using Websockets, using the Pusher API.
